ACETYLENE GENERATOR.

Application filed August 30, 1926. Seria1 No. 132,610.

This invention relates to gas-producing generators for the accommodation of dwell# ings and buildings upon the farm and in .the city alike. The generator is located within the ground a short distance from'the building, and the top thereof being exposed so as to facilitate the refilling of carbide, cleaning of interior, etc. l

The particular manner in which the device was designed throughout, renders 1t prefectly safe to use, and the gas produced thereby is very desirable for cooking and illuminating purposes, ,and the costthereof being much more economical than other systems. lt is entirely automatic in its operation, provides a dependable service, and being of a very substantial construction naturally will endure for a long period of time with only occasional attention.

One of the main objects of the invention is to improve a similar generator invented and patented August 6, 1918, yNumber 1,27 4,893, by Pius F. Killian.

`The invention has numerous advantages, all of which will be clearly pointed out during the progress of this description.

It is herewith understood that I reserve thev privilege of making certain minor changes in the details of construction, provided that same becomes an actual. necessity in the final perfectingof the device for the market, but not departing ,from the general principle disclosed.

Figure 13 illustrates lthe inner shell of the generator. i

Figure 14 is an enlarged section at, E-E of Fig. 11. n Figure 15 is a sectional view of the carbide container showing the openings in the bottom thereof.

The invention comprises a principal shell l, which is composed` of asuitable metal made up of telescopically engaged sections but not shown in the drawings, and of any dimensions desired. Said shellis enclosed by bottom 2 which is connected yto same by rivets 3 through corrugated flange 4, vand the top portion of same reinforced by band 5 and connected by rivets 6. Inner shell 7 is connected to main shell where shown by rivets 8, holes 9 forsame. Reinforcing band 10 is connectedhto top of shell 7 by rivets 11. Disposed within the shell 7 is the carbide container 12, and supported by hangers 13 which are secured to shell 7 where shown by rivets 14. p

The generator comprises two separate volumes of water, volume A for the lpurpose of, floating the bell 15, ywhile volume B is for generating gas by submitting to the action of carbide discharged therein, in a manner presently explained. Shell 7 separates the two volumes as shown. Gauge for volume B is shown at 16 and is connected by rivets 17, and overflow opening 18 in shell 7 as indicated. Inv order to provide proper weight forthe bell 15 heavy bands 19. are connected to `the lower portion thereof by rivets 20. Reinforcing plate 421 is secured to the underneath portion of the top of said bell byL any approved man ner, and threaded opening 22 to receive nipple 23 which accommodates valve 24 with handle-25 for same and secured thereto by .rivet 26. Lifting handles 27 are connected where shown by rivets 28. A suitable top 29 is provided for the shell 1,k and having a downward turned flange 80 extending around same anditting overt-op of said shell. One side of said top is retained to the shell by means of eye member 31 connected thereto by rivets 32, and hook member 33 which is connected to shell 1 by rivets 34, while the opposite side thereof is provided with a hasp 35 secured thereon by rivets 36, and staple 37 which is connected to said shell by rivets 38. A padlock may be used in connection with said hasp and staple if preferred. By referring to Fig. 4 it will be seen that hood 39projects from and forming a part of the top and secured thereto by rivets 40, and by soldering at the lines 41.

The container 12 is provided with a lid 42 for the purpose of filling same with carbide, said lid is pivotally connected by rivet 43, and is retained upon the opposite side by the latch 44, which is secured to said container by the rivets 45, also turned or rolled finger-hold 46 upon said lid. Lifting handles 47 are connected where .shown by rivets 48. l

A very important feature of the invention is the carbide feeding device, which follows:

It is understood from the foregoingdescription that the carbide is contained within member 12, of which the lower portion is funnel-shape, which would naturally direct same to the lower openingor spout 49 to which is connected hopper 50 by meansv of rivets 51. Said hopper having enlarged portions 52 with an opening therethrough to accommodate a horizontally disposed shaft 53 of which has threaded ends to receive nuts 54, said shaft supports the arms 55 of the shoe 56, holes in the arms for passage of said shaft. With reference to Fig. 1, itwill be seen that a portion of the. metal of the shoe 56 extends as at 57, thus retaining a small quantity of carbide therein and normally as shown. Lugs 58gwith opening therein, in said shoe to receive pin 59 connecting same with vertically disposed rod 60, plate 61 as shown, also housing 62 within said container to permit action of said rod. Carbide spreader 63 is provided as shown, and secured to member 64 by rivets 65, said member having connection with the vcontainer by rivets 66. Drain collars 67 and ,the rod 60 causing same to descend likewise and simultaneously actuating the shoe 56as indicated byV dotted lines in Fig. 11, and thereby discharging the carbide remaining in same directly into water volume B, thus generating additional gas which instantly rises and causes said bell to ascend thereby releasing said rod and thus restoring the feeding device to normal position as in Fig.

,1. This operation isV continuously and autoinatically repeated as long as there remains cleanse the gas before it is used, the lower' and upper portions of the filtery are packed with waste, as at 75, and hair well packed between at 76 and retained in position as indicated by wire netting 77 at the top and bottom thereof, and which is supported by angle strips 78 of which have connection with the filter by means of rivets 79. From within the filter the gas then passes through pipe 80, one end of which is secured to said ilter by threaded flange 81 with rivets 82 therefor, and the opposite end thereof to reducer 83. Main control valve 84 as shown, and a smaller valve 85, the latter being for the purpese of discharging foul gas when the generator being refilled with carbide, and thus purifying the newly generated gas, said control valve is closed during this operation to prevent the undesirable gas from passing on through the house service pipe. It will also be noted that both of aforesaid valves have permanently iiXed operating levers thereon. Continuing with the gas line, nipple 86, elbow 87, thence downward with nipple 88, packing nut 89 and sleeve 907 of which connect withy pipe 91. T connection 92 for the accommodation of pipe 93 through which the gas passes is directed to the building. Pipe 91 is continued downward and enters the generator by'means of elbow 94 and nipple 96 passing through opening in same with lock nut 95, see Fig. 5. This is for the purpose of returning to the generator water in said pipe caused by condensation therein. i.

Another important advantageof the invention is the method for agitating and removing the residue of the carbide which accumulates upon the bottom of the generator. For this purpose an agitator composed of a vertically disposed rod 97, which is bent at right angles at the lower part thereof, eX- tending as at 98 and forming a support for the framework, comprising members, 99, 100 and 101, both ends of said members being connected toy portion 98 by rivets 102. AV suitable housing or pipe 103 is provided and is supported and the top and bottom thereof by hangers 104 which are secured to shell 1 by rivets 105, also standard caps 106 with opening through same and lock nuts 107 in a ma-nner as shown in Fig. 2.

Bumper plates 108 are secured to shell 1 by rivets 109 in the arrangement as illustrated. After the removal of top 29 of generator the yrod 97 of which is square in shape, the upper end thereof is easily accessible for the application of a wrench or suitable tool for this purpose, upon which the framework thereof which rests upon the generator bottom may be put into an oscillating motion thereby thoroughly and effectively stirring and agitating the settlement therein from whence it is completely drawn out through the pipe 11,0, which enters the generator by means of a close nipple through an opening in same and elbows 111 as shown. Pipe 110 is enclosed at the top thereof by threaded cap 112, also hanger 113 for same and secured to shell 1 by rivets 114. Hangers 115 for pipes 80 and 91 are likewise secured by the rivets 116. By removal of said cap a pump may be applied thereto for purpose just described.

In preparing the generator for use the top 29 is removed therefrom and water is permitted to flow into space occupied by volume A which overflows through hole 18- of shell 7 and into space of volume B until it reaches the height of the gauge 16 upon which there is suiiicient water within the generator for all purposes required as aforesaid. Then by opening of lid 42 of container same is filled with carbide which permits a small quantity to enter the feeding device. Said lid is then closed and bell 15 is placed into position as shown in Fig. 1 with valve 24; open until same settles into volume A water upon which said valve is closed, top 29 is thereby replaced and the generator is ready for use. For refilling of carbide a similar operation is repeated.

Hood 39 of top 29 is for the purpose of protecting the'valves 811 and 85. The purpose of the packing nut 89 and sleeve 90 is to obtain a gas-tight joint and thereby rendering the pipe-line 91 and house service line 93 absolutely free from any possibility of leakage.

Again referring to Fig. 1 it will be clearly seen that the entire generator is embedded into the earth, the latter of which is illustrated at AB, with yonly the top portion thereof being exposed. In this manner space is not sacrificed and it is readily accessible to convenient operation. It will also be noted that the house service pipe-line is well under the surface of the ground thereby providing adequate protection `for same.

Having thus described my invention, what I claim as new is:

In an acetylene generator, a principal shell, an inner 'shell for said principal shell; a gas filter disposed upon the outer surface of the said principal shell; a pipe connecting both of the said shells permitting the gas to circulate from the gas chamber of the said inner shell to the aforesaid gas filter, and directed through a vertical pipe to the house service pipe-line; a main control valve in connection with the said pipe-line; an additional valve in the same for discharging foul gas from the generator while same is being refilled with carbide; a downwardly extending pipe from the house service pipe-line and returned into the generator to accommodate the action of natural condensation of water consumed.

In testimony whereof I affix my signature.
